Jeffrey Rosen, who served as acting attorney general at the end of the Trump administration, cited “ground rules” in refusing to tell lawmakers whether former President Donald Trump asked him for help in overturning the 2020 election results.

Rep. Gerry Connolly, a Democrat from Virginia representing the state’s 11th Congressional District, grilled Rosen on the topic during testimony before the House Oversight Committee on Wednesday. Specifically, the congressman asked Rosen if Trump pressed him or the department “to take any action at the department to advance election fraud claims or to seek to overturn any part of the 2020 election results.”
